Changing Font of DefaultMutableTreeNode

Hi!

I have a treenode and want to change the color and font of a treenode. I
have already implemented a TreeCellRenderer, but whenever I use that to
change the color of the font, the font of the whole tree changes. All I want
is to change a single TreeNode. What am I doing wrong?

private class LinkTreeCellRenderer extends DefaultTreeCellRenderer {
    public Component getTreeCellRendererComponent(JTree tree, Object value,
boolean sel, boolean expanded, boolean leaf, int row, boolean hasFocus) {
        super.getTreeCellRendererComponent(tree, value, sel, expanded, leaf,
row, hasFocus);
        Object nodevalue = null;
        if (!(value instanceof DefaultMutableTreeNode))
            return this;
        nodevalue = ((DefaultMutableTreeNode)value).getUserObject();
        if ((nodevalue instanceof Page) && ((Page)nodevalue.someattr)) {
            setFont(this.getFont().deriveFont(Font.BOLD));
            setTextNonSelectionColor(Color.BLUE);
        }
        return this;
    }
}

Thanks in advance,
Daniel
